* Cargo.lock: Update, to no longer use multiple versions of autocfg
* Update wasmtime-debug and wasmtime-profiling to current gimli 0.20.0
This also eliminates duplicate versions of gimli and arrayvec, and
eliminates the nodrop dependency entirely.
* Update wasmtime-profiling to goblin 0.1.3 and object 0.17.0
This also eliminates two duplicate versions of goblin, and duplicate
versions of proc-macro2, quote, syn, scroll_derive, and unicode-xid.
* Update wasmtime-profiling to current scroll 0.10.1
This eliminates duplicate versions of scroll.
* Update wasmtime-profiling to current target-lexicon 0.10.0
This eliminates duplicate versions of target-lexicon.
* Update wasmtime-interface-types to current walrus and wasm-webidl-bindings
This also eliminates the oldest of the three duplicate versions of
wasmparser.
* Update wasmtime-wast to current wast 8.0.0
This eliminates one of the duplicate versions of wast.
* Remove the `action` and `context` modules from `wasmtime_jit`
These modules are now no longer necessary with the `wasmtime` crate
fleshed out, and they're entirely subsumed by the `wasmtime` API as
well.
* Remove some more modules
* Document the `wasmtime::Instance` APIs
This documents oddities like the import list and export list and how to
match them all up. Addtionally this largely just expands all the docs
related to `Instance` to get filled out.
This also moves the `set_signal_handler` functions into
platform-specific modules in order to follow Rust idioms about how to
expose platform-specific information. Additionally the methods are
marked `unsafe` because I figure anything having to do with signal
handling is `unsafe` inherently. I don't actually know what these
functions do, so they're currently still undocumented.
* Fix build of python bindings
* Fix some rebase conflicts
* Update to the latest spec_testsuite and dependencies.
Update to target-lexicon 0.10, cranelift 0.54, wast 0.6, faerie 0.14,
and the latest spec_testsuite.
For wast and cranelift-wasm, update the code for API changes.
* Factor out the code for matching f32, f64, and v128.
This takes the idea from #802 to split out `f32_matches`, `f64_matches`,
and `v128_matches` functions, which better factor out the matching
functionality between scalar and vector.
* Remove `HostRef` from the `wasmtime` public API
This commit removes all remaining usages of `HostRef` in the public API
of the `wasmtime` crate. This involved a number of API decisions such
as:
* None of `Func`, `Global`, `Table`, or `Memory` are wrapped in `HostRef`
* All of `Func`, `Global`, `Table`, and `Memory` implement `Clone` now.
* Methods called `type` are renamed to `ty` to avoid typing `r#type`.
* Methods requiring mutability for external items now no longer require
mutability. The mutable reference here is sort of a lie anyway since
the internals are aliased by the underlying module anyway. This
affects:
* `Table::set`
* `Table::grow`
* `Memory::grow`
* `Instance::set_signal_handler`
* The `Val::FuncRef` type is now no longer automatically coerced to
`AnyRef`. This is technically a breaking change which is pretty bad,
but I'm hoping that we can live with this interim state while we sort
out the `AnyRef` story in general.
* The implementation of the C API was refactored and updated in a few
locations to account for these changes:
* Accessing the exports of an instance are now cached to ensure we
always hand out the same `HostRef` values.
* `wasm_*_t` for external values no longer have internal cache,
instead they all wrap `wasm_external_t` and have an unchecked
accessor for the underlying variant (since the type is proof that
it's there). This makes casting back and forth much more trivial.
This is all related to #708 and while there's still more work to be done
in terms of documentation, this is the major bulk of the rest of the
implementation work on #708 I believe.
* More API updates
* Run rustfmt
* Fix a doc test
* More test updates
* Tweak the API of the `Val` type
A few updates to the API of the `Val` type:
* Added a payload for `V128`.
* Replace existing accessor methods with `Option`-returning versions.
* Add `unwrap_xxx` family of methods to extract a value and panic.
* Remove `Into` conversions which panic, since panicking in `From` or
`Into` isn't idiomatic in Rust
* Add documentation to all methods/values/enums/etc.
* Rename `Val::default` to `Val::null`
* Run rustfmt
* Review comments
* Rename the `wasmtime_api` library to match the containing `wasmtime` crate
Commit d9ca508f80 renamed the
`wasmtime-api` crate to `wasmtime`, but left the name of the library it
contains as `wasmtime_api`.
It's fairly unusual for a crate to contain a library with a different
name, and it results in rather confusing error messages for a user; if
you list `wasmtime = "0.7"` in `Cargo.toml`, you can't `use
wasmtime::*`, you have to `use wasmtime_api::*;`.
Rename the `wasmtime_api` library to `wasmtime`.
* Stop renaming wasmtime to api on imports
Various users renamed the crate formerly known as wasmtime_api to api,
and then used api:: prefixes everywhere; change those all to wasmtime::
and drop the renaming.
* Migrate back to `std::` stylistically
This commit moves away from idioms such as `alloc::` and `core::` as
imports of standard data structures and types. Instead it migrates all
crates to uniformly use `std::` for importing standard data structures
and types. This also removes the `std` and `core` features from all
crates to and removes any conditional checking for `feature = "std"`
All of this support was previously added in #407 in an effort to make
wasmtime/cranelift "`no_std` compatible". Unfortunately though this
change comes at a cost:
* The usage of `alloc` and `core` isn't idiomatic. Especially trying to
dual between types like `HashMap` from `std` as well as from
`hashbrown` causes imports to be surprising in some cases.
* Unfortunately there was no CI check that crates were `no_std`, so none
of them actually were. Many crates still imported from `std` or
depended on crates that used `std`.
It's important to note, however, that **this does not mean that wasmtime
will not run in embedded environments**. The style of the code today and
idioms aren't ready in Rust to support this degree of multiplexing and
makes it somewhat difficult to keep up with the style of `wasmtime`.
Instead it's intended that embedded runtime support will be added as
necessary. Currently only `std` is necessary to build `wasmtime`, and
platforms that natively need to execute `wasmtime` will need to use a
Rust target that supports `std`. Note though that not all of `std` needs
to be supported, but instead much of it could be configured off to
return errors, and `wasmtime` would be configured to gracefully handle
errors.
The goal of this PR is to move `wasmtime` back to idiomatic usage of
features/`std`/imports/etc and help development in the short-term.
Long-term when platform concerns arise (if any) they can be addressed by
moving back to `no_std` crates (but fixing the issues mentioned above)
or ensuring that the target in Rust has `std` available.
* Start filling out platform support doc
* Fix fuzz target compilation.
* Bump version to 0.7.0
* Temporarily disable fuzz tests
Temporarily disable fuzz tests until https://github.com/bytecodealliance/cranelift/issues/1216 is resolved.
* Fix publish-all.sh to not modify the witx crate.
* Remove the "publish = false" attribute from Lightbeam.
* Add a README.md for wasmtime-interface-types.
* Remove the "rust" category.
This fixes the following warning:
warning: the following are not valid category slugs and were ignored: rust. Please see https://crates.io/category_slugs for the list of all category slugs.
* Mark wasmtime-cli as "publish = false".
* Sort the publishing rules in topological order.
Also, publish nightly-only crates with cargo +nightly.
* Allow using WASI APIs in the Python extension
This commit adds support to the Python extension to load the WASI
implementation when a WASI module is seen allowing Python to load
WebAssembly modules that use WASI. This is pretty primitive right now
because there's no way to configure the environment/args/preopens/etc,
but it's hoped to be at least a start!
* rustfmt
* Refactor checks for the wasi module name
* Move the check into `wasmtime-wasi` itself
* Make it conservative for now and match anything that says `wasi*`
* Leave a `FIXME` for improving this later on
* Enable missing feature of winapi for `winx`
* General Cargo.toml cleanup.
- Remove travis-ci attributes.
- Remove "experimental" badges from actively-developed crates.
- Reflow some long lines.
- Use dependency features consistently.
- Add readme attributes
* Update WASI to the latest trunk.
This notably adds a .gitignore file for the WASI directory.
